Application architectures have evolved greatly over the last 30 years of computing. Theyve shifted back and forth from proprietary character-mode terminals with centralised processing to client-server applications with distributed processing. Then, they shifted to the centralised hosting of applications but this time with open standards-based, web-delivered front-ends. Each of these trends included a variety of methods to connect disparate systemsmany proprietary, some without any re-usable characteristics and all typically requiring the developers, operators and maintainers to learn a new set of skills and the organisation to put new processes in place. These upheavals invariably created friction and frustration for the individuals and the organisation involved.
